Penrith homes use the most power after sunset, when the air conditioning is still running and the panels have stopped producing. Clean Earth Solar installs solar batteries across Penrith so the power your roof makes at midday runs the house through the evening.
We size every battery from your own usage data, then our SAA-accredited electricians install it, commission it and set up the monitoring with you.
Most Penrith enquiries are battery retrofits on an existing system. If you’re starting from scratch, our solar panel installation in Penrith team quotes panels and storage together.
Not sure your inverter can take a battery?
Every Penrith battery we install is designed and fitted by our own team: SAA-accredited electricians and electrical apprentices, with no subcontractors, roofers or labourers on site. The person who assesses your home is one of our trained installers.

Penrith is one of the hottest parts of Sydney. The Bureau of Meteorology recorded 48.9°C at Penrith Lakes on 4 January 2020, the highest temperature in NSW that year, and Penrith City Council runs a dedicated Cooling the City Strategy because urban heat is a standing local issue.
That heat shapes the electricity bill. Hot afternoons roll into warm evenings, so the air conditioning keeps running after the panels stop, right through the hours most time-of-use tariffs charge the most. A battery stores the midday surplus that would otherwise earn a small feed-in credit, then runs that evening load on it.
Batteries can limit their output when the air around them gets too hot, so we plan the location for it, favouring a garage or a shaded south or east wall over a west wall that takes the full afternoon sun, and we keep the clearances required under AS/NZS 5139, the Australian standard for battery installations.
Backup needs switchboard room for extra protection and a separate section for the circuits that stay live. Older boards with ceramic fuses, or boards already full, are usually replaced, and that cost is in the written quote before work starts. Penrith sits on the Endeavour Energy network, and we lodge the connection application on your behalf.
Compact two-storey homes in newer estates such as Jordan Springs and Glenmore Park often have limited wall space, so a garage install is common. Single-storey homes on larger blocks usually have more placement options, and rural-residential properties out towards Mulgoa and Londonderry are where three-phase supply and pump loads come up most.

A battery is sized from your interval usage data, not from the size of your roof. Your retailer’s half-hourly data or your existing monitoring shows what the house draws overnight, and how much surplus your panels produce at midday to charge it.
Two goals pull the size in different directions. A bill-focused battery should empty most nights, because unused capacity is money spent for nothing. A backup-focused battery is set by the circuits that must stay live in an outage, such as the fridge, internet, lights and a pump. We also plan for loads coming in the next few years, such as an EV or a pool.
If you want to run the numbers before we visit, our guide to sizing a solar battery walks through reading your bill and splitting daytime from overnight use.
Every Penrith battery is quoted in writing after a site assessment. The main price factors are:
Battery incentives from the federal and NSW governments change regularly, so we confirm what your address and system qualify for at quote time and show it on the quote. Current program details sit in our breakdown of NSW and federal solar battery rebates.
Our crews work across the Penrith LGA, including Penrith, Emu Plains, Leonay, Jamisontown, Glenmore Park, Mulgoa, Kingswood, Cambridge Park, Werrington, St Marys, St Clair, Erskine Park, Jordan Springs, Cranebrook, Castlereagh and Londonderry.
We also install batteries further up the hill in the Blue Mountains, where outages make backup a priority, and right across Western Sydney.
The hottest evenings of the year are when a battery earns its keep, and summer is when installation calendars fill. Clean Earth Solar will look at your usage, your switchboard and your inverter, then tell you plainly whether a battery makes sense for your Penrith home and which one.
Send us a recent bill and we’ll take it from there.
In most cases, yes. A hybrid or battery-ready inverter makes it a straightforward addition, while an older string inverter may need an AC-coupled battery or a new inverter. We check your inverter and panel output during the assessment and tell you which applies.
Only if it's installed with backup configured. Most homes back up selected circuits such as the fridge, lights, internet and a pump, and three-phase homes wanting whole-home backup need a battery built for it, such as the Sungrow SBH. We agree the backed-up circuits with you before the quote is finalised.
The price depends on battery capacity, your supply type, backup scope, inverter compatibility and switchboard work. Clean Earth Solar gives you a fixed written quote after a site assessment, with any eligible incentives shown on it.
A straightforward retrofit is usually done in a day. Network approval and any switchboard upgrade add lead time beforehand, and we give you the timeline when the quote is accepted.
